JONATHAN HERSHBERGER, OF WALNUT CREEK, ASSIGNOR OF ONE-HALF TO WILLIAM M. JOHNSTON, OF WILMOT, OHIO.

THRASH|NG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 469,184, dated February 16, 1892.

Application filed MarchZl, 1891.

T0 at whom it may concern:

Be it known that I, JONATHAN HERSHBER- GER, of Walnut Creek, in the countyof Holmes and State of Ohio, have invented certain new and useful Improvements in Thrashing-Ma-- chines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon, in which Figure 1 is a perspective view. Fig. 2 is a .distributing board. Fig. 5 is a side elevation.

Fig. 6 is a view of the straw-elevating device, showing the rear side or portion of said strawelevating device, together with the vibratingfinger mechanism.

The present invention has relation to thrashing-machines; and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claims.

Similar letters of reference indicate corre-' sponding parts in each figure of the drawings.

In the accompanying drawings,Areprese nts the frame of the machine, which frame is constructed as to form and size with reference to the parts hereinafter described. The thrashing-cylinder Bis constructed in the ordinary manner and is properly journaled to the frame A in the ordinary manner. To the rear of the cylinder B are located the straw elevator and check-board, which elevator is inclin ed rearward from the cylinder. The shafts a and b are properly journaled to the frame A and are provided with the rollers or pulleys c, and in the event sprocket-chains are used for attaching the bars d, sprocket-wheels should take the place of the pulleys c. The bars d are securely fastened to the belts or drive.- chains 0 and extend entirely across the inner part of the machine proper. The bars 61 are provided with the lifting-fingers e, which lifting-fingers are attached to the bars 01 in any convenient and well-known manner.

For the purpose of preventing coarse straw from entering between the bars d the inclined Serial No. 385,937- (No model.)

slats are provided, which slats are attached at their ends to the frame A in any convenient manner, and are so arranged thatthe chaff and grain which pass between the bars 01 will fall between said inclined slats d.

To the top or upper part of the frame Ais located the dome D, which dome is located substantially as shown in Figs. 1, 2, 5, and 6. At the rear of the straw-elevating device are located the vibrating fingers E, which fingers straw to the top or upper part of the dome D, at

which time it falls upon the vibrating fingers E andthe returnlifting-fingerseandpass esdown between the check-board F and the return lifting-fingers, when it is delivered upon the picker-arms h and the bars h, from whence the straw is conveyed to the rear end of the machine.

For the purpose of preventing the straw from clogging either in the top of the dome D or at the bottom of the check-board F the vibrating fingers E and g are provided, which vibrating fingers are for the purpose of agitating the straw and preventing the same from clogging and at the same'tilne assisting in the separation of the grain from the straw.

For the purpose of better separating the grain from the straw the slats G are provided, which slats are located directly above the check-board F, which check-board receives the grain and fine chaff which pass between the slats G. For the purpose of preventing the grain and chaif which fall on checkboard F from again falling in the straw the check-board is provided with the V-shaped flange, which carries the grain and chaff to each side of the machine, where they are conducted to the endless apron H. The pickerarms h are securely attached to the shafts M, which shafts are journaled to the frame A and rotary motion communicated to said picker-shafts k by means of the pitman 71 and the cranks h It will be understood that a pulley is to be attached to one of the pickershafts h and rotary motion communicated to the picker-shaft provided with a pulley by means of abelt or its equivalent. The picker-arms h are bent or curved, as illustrated in Figs. 2 and 3, and are located between the bars h. These picker-arms h are rotated in such a direction that when they are brought above the bars 71/ they will travel or move toward the rear end of the machineproper. For the purpose of preventing the straw from wrapping the picker-arms h are curved, as illustrated in the drawings, thereby preventing the points of said pickerarms h from carrying or drawing the straw between the bars h. The picker-shafts h are located at such a distance apart that the ends of the arms It will slightly interlock, thereby carrying the straw from one set of picker-arms to the next adjacent set, and so.

on until the straw is delivered at the rear end of the machine. It will be understood that by providing the picker-arms h and locating them as above described and shown in Fig. 2 the grain and chaff will be thoroughly sepa rated from the straw. For the purpose of conveying the grain and chaff which pass between the picker-arms h and the bars h the endless apron H is provided, which extends from the rear end of the machine to the forward end, and is propelled by means of a pulley and belt in the ordinary manner or their equivalents.

For the purpose of carrying the grain and chaff toward the front of the machine and delivering the same at the proper place with reference to the fan I the return-board is provided.

The return-board J is attached to the sides of the machine proper and extends rearward over the sieves locatedin the rear of the fan I.

The sieves used in this machine are attached in the ordinary manner and are of the usual form and are located and adjusted in the ordinary manner.

For the purpose of conveying the grain and chaff to the proper place in the rear of the fan the return board or bottom K is provided, which is located as shown in Fig. 2, and, as shown, the bottom or return board K extends rearward to a point, so as to discharge the grain and chaff, which pass through the endless apron H in front of the return-board J in the rear of the fan I.

For the purpose of vibrating the fingers E and g the rock-bars g and -g are provided with the arms 70, to which arms are journaled the pitmen The pitnien k are journaled to the crank ha substantially as illustrated in Fig. 6. For the purpose of communicating rotary motion to the crank k the pulley k is provided, which pulley is rotated by means of the belt 70 or its equivalent.

The bars h are preferably formed as illustrated in' Fig. 3, which consists informing said bars upon their upper sides V-shaped, and are so formed for the purpose of preventing the straw from lodging upon said bars and at the same time inclosing or covering the picker-shafts 71 The flanges l are provided and are so located that they will protect or cover the portions of the shafts 71 between the bars 71.. It will be understood that the grain will better pass between the bars 71 by reason of the inclined faces located upon the upper sides of said bars.

. .For thepurpose of conveying the grain and chaff which pass between the bars 01 and the inclined slats d to the endless apron H in front of the picker-shafts W the returnboard-K' is provided, which return-board is attached to the sides of the machine proper and is located between the elevating device, substantially as illustrated in Fig. 2.

It will be understood that by providing the return-board K the grain and chalf which are separated during the time that the straw is elevated to the top of the dome D will not be received or mingled with the straw at the time the straw is received on the pickerarms. It will also be understood that the grain and chaff which are separated from the straw as it descends from the top of the dome D to the picker-arms will fall on the check-board F and be carried to the sides of the separator and not allowed to mingle with the straw.
